  DMK/LD

  DMK/LD (single-position re-engagement / multi-position re-engagement - backlash-free - with roller technology) 'DMK/LD' are double supported and based on the backlash-free standard safety couplings from GERWAH's product portfolio. The couplings are designed to stand high dynamic and radial loads. The flange mounting allows simple and comfortable assembly.

  DMK/B

  DMK/B (single-position re-engagement / multi-position re-engagement - backlash-free - with roller technology) Axial, radial or angular: GERWAH's backlash-free safety coupling 'DMK/B' easily compensates any misalignments. The system has been designed to connect two shafts with a metal bellow which serves as a torsionally rigid compensation element. That way, the coupling guarantees for the safety of the entire facility even under high dynamic load.

  DMK/E

  DMK/E (single-position re-engagement / multi-position re-engagement - backlash-free - with roller technology) The backlash-free 'DMK/E' couplings made by GERWAH impress with a torsionally elastic compensation element based on an elastomeric spider which damps occurring vibration during performance. The coupling is designed as a plug-in element and available with clamping hubs, inner or outer cone hubs. High dynamic loads is not a problem for 'DMK/E'.

  DXM/CD

  DXM/CD (multi-position re-engagement / single-position re-engagement - backlash-free - with balls) The backlash-free coupling 'DXM/CD' is characterized by its two robust ball bearings. Thanks to the system's flange mounting, sprocket wheels or pulleys can be added easily and higher radial loads do not cause any problem. This coupling is available with a parallel key or with cone hub.

  DXM/N(L)

  DXM/N(L) (multi-position re-engagement / single-position re-engagement - backlash-free - with balls) GERWAH's 'DXM/N(L)' is suited perfectly for the transmission of torques from 5 to 450 Nm. Until reaching the disengaging point, the system transmits the driving force without backlash. At overload, a high-speed cut-out takes effect within milliseconds. Torque can be adjusted freely during assembly. The system is available with short and long hubs as well as with parallel key or cone hub

  DXM/ND

  DXM/ND design with two bearings (multi-position re-engagement / single-position re-engagement - backlash-free - with balls) When safety couplings have to stand heavy loads, GERWAH's 'DXM/ND' with two ball bearings is the ultimate choice. The system boasts a robust design and can be assembled easily thanks to flange mountings. At overload, torque is reduced immediately to protect other parts of the facility.

  DXM/E

  DXM/E (multi-position re-engagement / single-position re-engagement - backlash-free - with balls) GERWAH's backlash-free 'DXM/E' is equipped with an elastomeric spider which serves as a torsionally rigid compensation element and damps vibration reliably. The system has been designed to connect two shafts and to compensate axial, radial, and angular misalignments. It is ideally suited for the transmission of torques from 50 to 1,200 Nm.

  DCM/S

  DCM/S - single-position re-engagement coupling and activation single-position re-engagement coupling GERWAH'S 'DCM/S' offers extremely easy torque adjustment. When the chosen limit is exceeded, the coupling disengages automatically. The coupling re-engages in a 360-degree position only. The activation single-position re-engagement variant must be re-engaged manually.

  DCM/D

  DCM/D - multi-position re-engagement coupling At overload, the multi-position re-engagement coupling 'DCM/D' made by GERWAH disengages in regular angular distances depending on its size. It has been designed for the transmission of torques from 50 to 1,400 Nm and is available with an elastomeric spider to connect two shafts. In order to adapt the coupling to the customers' individual needs, the torque can be adjusted easily.

• DCM/V

  DCM/V activation and interlocking coupling The 'DCM/V' system is available as interlocking and as activation coupling. The interlocking system is equipped with a limit switch which signals overloads without interrupting the transmission of the torque when the chosen maximum torque is exceeded. The activation coupling has to be re-engaged manually once it has disengaged.
